CNC program fails at LIN moment Vel = 0.0 m/s dispite $Vel_CP = 0.005 m/s-JeffNickel-04-13-2020
My .scr files fail because when the g-code points are joined together with LIN movements the LIN commands have Vel=0 m/s . These lines of LIN commands are proceeded by a %Vel.CP = 0.00500 line but the system complains about the vel = 0 m/p parameter.
$VEL.CP = 0.00500

The g-code contains a G1Z-0.079F11.8 line near the top. F11.8 in/min converts to 0.005 m/s I guess this is wherethe $Vel.CP = 0.00500 get this value from.
Should the LIN movements not have Vel = 0.005 m/s values or should these be over-ridden by the %Vel = 0.00500 command?
Also, these LIN movements are CONT with C_DIS = 1mm For CNC machining should we be using approximate paths?
Thanks,
Almost there,
Jeff

Hi Jeff,
The following link shows how you can select and modify a post processor for a specific purpose:
//m.sinclairbody.com/doc/en/Post-Processors.html#SelectPost
If you want to have 3 decimal values for the speed in your FOLD section:
- Locate your post file. Example: C:/RoboDK/Posts/KUKA_KRC4_DAT.py
- Look for the section where you output a linear or joint moves (search FOLD LIN for example)
- You'll see the formatting string and you can set it to 3 decimal values. Example:
Code:
;FOLD LIN P%s %sVel=%.3f m/s
